The Model 1210 trace gas detector locates leaks in finished products, parts, and subassemblies. Uson's Leak Locator pinpoints leaks that are difficult or impossible to find with soap film, dunk tanks, and other mechanical techniques. The rugged Uson Model 1210 is well suited to demanding, high-speed manufacturing operations in a wide variety of industries.

• Rapid response.
• Rugged construction.
• Multiple alerting functions.
• Locates the position of the leak.
• Detects two gases: helium or argon.

• Controls trace gas supplied to the test part.

• Tests diverse products in multiple industries
• Extremely fast setup-no calibration required.

Base Unit

The stationary unit contains the main display, the program memory, the electronics to process signals from the handset, and pneumatics to control gas to the product under test.

Display

Setup the tester using a large touch screen display with simple menus. The 5.5 inch screen shows a real-time scrolling graph of gas concentration.

Programs

Two programs can store setup parameters for two different tests.

Electronics

Power supply, main electronics, and gas control logic are housed in the upper portion of the rugged base unit enclosure. The enclosure is NEMA-4 rated for industrial environments.

Pneumatics

Two valves and relays for the introduction of the trace gas into the test part are contained in the lower section of the NEMA-4 base. More valves and relays can be added.

Handset

The unique sensor/indicator sets the Leak Locator apart from other trace gas detectors. The handset offers four methods to alert the user to leakage-

• Audible tone

• Vibration in handle

• LCD numeric reading

• Extra-bright flashing red LED

By using the tone and/or vibration functions, operators can watch where the sensor is placed and still get information about potential leaks. Any or all alert functions can be active at once. Each alerting method provides feedback to the user proportional to the amount of trace gas detected at the leakage point.

Included with the handset are three different nozzles: 7 inch, 12 inch, and 24 inch.

The auto zero function adjusts for ambient trace gas and room humidity to improve speed and efficiency.

'The Leak Locator is extremely easy to set up and operate."

Operation

The Leak Locator is perfect for testing a wide range of manufactured products and assemblies in which the leak location must be identified quickly and efficiently. For initial setup, the operator or setup personnel establish merely a few parameters:

Sensitivity

The unit can be set for one of eight sensitivities. The lower the sensitivity, the faster the recovery time. The sensitivity selected will be based on the amount of leakage anticipated and the required testing speed.

Valve Activation Steps

The Model 12 1 0 supplies valving and valve control to supply the trace gas (helium or argon) to the product under test. If the Model 12 1 0 is to control the helium or argon, the valve times are set as well as the valve sequence. This is a very simple procedure because the base unit's large display provides full menu choices.

Pneumatic configurations are available for low flow or high flow part-filling applications.

Main Menu on Touchscreen Display

Tracer Gas

Select either helium or argon as the tracer gas. Helium provides the greatest sensitivity.

Alert Methods

Set the alert method desired. Any or all alert methods can be active at the same time.

Ready to Test

After setup parameters are established, the Leak Locator can be used almost immediately following a brief warmup. Tests can be started at the base unit or by pressing the button on the handset.
